I do find that you can get some great renders that are quick just through simple lighting - my technique is to create primitives (spheres for general lighting and planes for more directional) and making them emissive via the surface configuration.
Although I was expecting more precise info, a big thanks.
So if I get it right, you've increased your RAM from x? to 64Go, changed your CPU to a more powerful one but kept the same graphic card ?
From the little experience I have, I believe that RAM size doesn't have much influence on render times unless you have to load a lot of complex textures (skins, hair, etc) :
on most of the renders I've done, the RAM usage is around 10-12 Go only
CPU usage is very high, can go up to 100%
But I believe the key to fast renders is a powerful NVIDIA card (4Go) or even better, 2 cards.
What do you call Sphere ? Is that the (sky)dome ?
From what I see in your images above :
- you turn the Camera Headlight off
- you use many other light sources like the light emissive Hotel sign or, on the same pic, the light above the door.
To me, that's complex lighting.
It would be nice that other IRAY users join the discussion.
Maybe we can start a separate thread ?
